IMPROVEMENT IN HEMMERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 96,901, dated November16, 1869.

To all whom it may concern:

Be it known that I, THOMAS H. EULASS, of Mason City, Mason county,Illinois, have in vented a new and useful Adjustable-Hemmer forSewing-Machines; and I hereby declare the following to be a-full, clear,and exact de scription thereof, reference being had to the accompanyingdrawings, making part of this specification.

My invention relates to a hemmer for sewing-machines whichhas theordinary means of attachment and adjustment upon the clothplate, andwhich has also a means of adjust ment, as hereinafter described, bywhich wider German silver, white metal, or other suitable material. Itslower portion or base A lies flat upon the cloth-plate of thesewingmachine when in use, and is connected by a fold, a, with aportion, A, a part of which lies flat upon the base A, while a partextends beyond the base, as shown in Figs. 1 and 2. Connected with theportion A by a semicircularly-curved portion, B, is the scale-plate U,which plate has a slot, 0, extending from the curved portion B to nearthe end of said plate, and upon each side of the slot is marked a scale,0.

Between thetwo plates A and O is introduced a turning piece or plate, E,formed of cast or sheetmetal, as preferred, and having on one side asomewhat spirally-shaped groove or rabbet, e, which groove acts inconjunction with the under side of the scale-plate to turn the edge ofthe cloth.

The plate E has a screw-threaded hole, 6,

for the reception of a thumbscrew, F, which passes through the slot 0,and by which the piece E is secured, at the desired adjustment, theplate 0.

The base A has an extension or arm, Gr, having a slot, g,'to admit theordinary thumbscrew, by which the hemmer is securedto the cloth-plate ofthe machine.

By a slight modification of the arm G the hemmer is made to suit othersewing-machines besides the Florence.

The operation of my hemmer isas follows The ends of the turning-piece E(which project slightly beyond the edges of the scaleplate 0) areplaced, by thescales c, to the desired width for the hem. Thethumb-screw Fis then tightened, so as to secure the turning-piece inplace. The hemmer is then socured to the cloth-plate of thesewing-machine by means ot'the ordinary thumb-screw passing through theslot g. The edge of the cloth to be hemmed is passed between theturningpiece E and the portion A, and being turned over within thecurved part B the immediate edge is turned by the rabbet in the piece E,thus forming a complete fold or hem, which is secured by stitching, inthe ordinary manner.

It will be seen that by adjusting the turning-piece the hem may be madeof any desired width within certain limits. I

I claim As a new article of manufacture, the hemmer herein shown anddescribed, consisting of plate A A B (J G, formed as described, andhaving slots 0 g, scales 0 c, and adjustable edge-turning block E andset-screw F.

In testimony of which invention I hereunto Set my hand.
